This is a hands-on, practical guide to describe field trials in oil palm. The location for field trials is key, as is land preparation. Other logistics include the germination of seeds from crossing programmes, planting in a nursery and well-grown seedlings for field planting. The trial design needs to be translated into field lay out. Field planting is a critical point requiring plant care, good labelling, field lining and a system of checks, and must be timed to the rainy season. Recording of trials starts 1 year after planting for crown disease assessment and continues for yield approximately 30 months after field planting. Growth measurements also begin 30 months after planting. Tests for oil yield and quality are carried out one year after yield recording.

The oil palm is a remarkable crop, producing around 40% of the world’s vegetable oil from around 6% of the land devoted to oil crops. Conventional breeding has clearly been the major focus of genetic improvement in this crop. A mix of improved agronomy and management, coupled with breeding selection have quadrupled the oil yield of the crop since breeding began in earnest in the 1920s. However, as for all perennial crops with long breeding cycles, oil palm faces immense challenges in the coming years with increased pressure from population growth, climate change and the need to develop environmentally sustainable oil palm plantations. In Oil Palm: Breeding, Genetics and Genomics, world leading organizations and individuals who have been at the forefront of developments in this crop, provide their insights and experiences of oil palm research, while examining the different challenges that face the future of the oil palm. The editors have all been involved in research and breeding of oil palm for many years and use their knowledge of the crop and their disciplinary expertise to provide context and to introduce the different research topics covered.

The 2019 Extra Joint FAO/WHO Meeting on Pesticide Residues (JMPR) was held in Gatineau/Ottawa, Canada from 7 to 17 May. The FAO and WHO Joint Meeting on Pesticide Residues (JMPR) is an expert ad hoc body administered jointly by FAO and WHO in the purpose of harmonizing the requirement and the risk assessment on the pesticide residues. The JMPR meets annually to evaluate possible hazards to humans arising from the occurrence of pesticide residues in foods. The Evaluation monographs of pesticide residues in food 2019-Part I (e-version only) includes summary of the residue data considered by the 2019 JMPR. The JMPR is the only scientific advisory body to service the Codex and FAO member countries in risk assessment of pesticide residues and in establishment of Codex MRL in food and feed. The JMPR report and evaluations are the unique technical publications in the review of pesticide residue data from around the world. The Report provides the evaluations of the Joint Meeting of the FAO Panel of Experts on Pesticide Residues in Food and the Environment and the WHO Core Assessment Group on Pesticide Residues. The extra Meeting evaluated 19 pesticides, including eight new compounds and three compounds that were re-evaluated for toxicity or residues, or both, within the periodic review programme of the Codex Committee on Pesticide Residues (CCPR).

This book contains the proceedings of the `8th Nitrogen Workshop' which was held at the University of Ghent, Belgium, from 5 to 8 September 1994. Although nitrogen dynamics in different ecosystems have been studied for several decades, new orientations and other emphases have recently emerged. Previously, nitrogen was considered as an essential element mostly in terms of productivity, but now, more emphasis is attached to environmental consequences. More than 100 contributions in this book tackle recent developments within the fields of nitrogen advice systems, plant response to fertilization, immobilization and mobilization, nitrification, denitrification, leaching, ammonia volatilization and biological nitrogen fixation. A large number of papers is devoted to the formation of gaseous nitrogen compounds, while mineralization-immobilization is another topic of important interest. The book also contains the reports of discussion groups on different aspects of the nitrogen cycle.

This is a hands-on, practical guide to general and specific practices in oil palm nurseries to produce healthy, vigorous and uniform plants ready for field planting. There are two nursery stages, pre-nursery and main nursery. The pre-nursery receives both germinated seeds and tissue culture produced plantlets (ramets) which are planted in a relatively small area in which shade and humidity can be controlled. Once young plants are established they are transferred to the main nursery, potted-on and grown on to produce field-ready plants. Good nursery practices, using sustainable approaches where possible, aim to provide high quality planting materials for both commercial production and field trialling. This is an invaluable manual for commercial seed producers, nursery plant producers, commercial plantation companies and plant breeders, as well as researchers in oil palm. It is useful for those starting a career in oil palm production, and as a reference guide for managers and for training purposes.

Plant pathogens cause significant economic losses and endanger agricultural sustainability. The emergence of new plant diseases is caused primarily by international trade, climate change, and pathogens' ability to evolve quickly. Rapid and accurate identification of plant pathogens is critical for disease management. The diversity and distribution of plant pathogens, on the other hand, can significantly impede disease management and diagnostic efforts. Plant pathogens employ a number of strategies that result in diversity, transmission, and host adaptation. Plant pathogens have been observed interacting with a wide range of host species such as plants, endophytes, insects, pollinators, and other plant pathogens. However, the transmission and evolution of plant pathogens in hosts, as well as the impact of pathogens on different hosts, are often unknown.

The oil palm is the world's most valuable oil crop. With palm oilproduction increasing by more than 50% in the last decade of thetwentieth century and set to double in the next twenty years, ithas never before been so important to understand the history, useand cultivation of this fascinating crop. There have been many new developments since the third edition ofThe Oil Palm in 1988, particularly in the fields of clonalpropagation, agronomy, breeding and molecular genetics. This newedition has been completely rewritten, and is the first book torecord and explore these and many other developments. The book traces the origins and progress of the industry, anddescribes the basic science underlying the physiology, breeding andnutrition of the oil palm. It covers both cutting-edge research,and wider issues such as genetic modification of the crop, thepromise of clonal propagation, and the effects of palm oil on humanhealth. The practical problems of maximising yield of oil andkernels are discussed in relation to the present 'yield gap' andoil extraction rate decline in Malaysia. The oil palm is alsocompared to the soya bean and other oil crops, and the recenthistory of the price of oil palm products is considered in thelight of this. The Oil Palm makes an essential contribution to oil palmresearch and will be an indispensable reference and guide foragricultural students, researchers and all those working,worldwide, in the oil palm industry.

Annotation. Diseases caused by Ganoderma species cause major losses of palms and other perennial crops throughout the world, and these are particularly significant in Asia. Successive replanting of crop monocultures can be rapidly exploited by soil borne fungi such as Ganoderma, and the problem will become more serious in the 21st century, as more areas become due for second or even third replanting. Environmental considerations will reduce exploitation of new forest areas, making further replanting of these crops inevitable. Thus, appropriate, integrated management systems for these diseases are vital. However, the development of such control measures has been hampered in the past by a limited knowledge of the nature and inter-relationships of populations of different hosts and the mechanisms of disease establishment and spread.This book aims to address these limitations through enhanced knowledge of the biology and taxonomy of Ganoderma species. The use of molecular and biochemical methods can be used to provide a greater understanding of the spread of the pathogen, and consequently, the improved management of disease.
